To all whom 'itimay concern:

Be it known that I, WILLIAM RIGIITER CoMINGs, a citizen of the United States, residing at'London, in the county of Surrey,

England, have invented new and useful Improvements Yin Box-Making Machines, of which the following is a specication.

My invention relates to the manufacture of boxes, and is designed either to manufacture the box or lid itself, or to cover a previously made box or lid.

Said invention is primarily designed to manufacture or cover cardboard or other' paper boxes and' lids, though the mechanism 1s applicable to the manufacture of boxes and l1ds of metal. According to this invention, -it is proposed to employ mechanism of substantially the following kind, the description 'being mainly devoted to the action when covering a previously made box or lid, and from this description the action of makinga box only, or of making a box and covering it at the same time, will be readily understood.

A folding die or mechanism is provided havin hinged or flexible wings adapted to fold t e covering contact with the sides of the box, and afterward by its continued action turnthe covering material, if desired, around the top edge of the box and fold it into the inside, and fixv it there when required. The die workin in this Way may be termed a double acting olding die, tion may also' be made triple acting when it is desired to make or cover a ianged box. In the latter case the first action is to fold the covering blank over the flange and press Vit intothe corner angle between the iange and the box body; the second'action Is, as before, to fold up the sides and corners; and

, the third act-ion turns the flaps over the edges into the inside 'of the box. ing die is operated by any suitable actuating mechanism in such a manner as to cause'the three actions to follow on in sequence and may be .completed during a single stroke or turn of the driving power, after which, during the return stroke, the die opens out and resumes its original position so that the completed or covered box can be removed or ejected from the die by any suitable mechanism. y

When desired, the die can be adapted to fold up a single blank into the form of a blank up into close fitting4 are, respectiv y, a or by suitable modifica-p This fold? v plain or uncovered box, but its most common and useful function is to cover with plain or fancy materials a box-body or blank that has been previously prepared by some other machine or by hand.

It is preferred to arrange the actuating mechanism of the die so that its several actions are, without intermission, sequences of one continuous motion, but these sections can also be worked in separate stages of intermittent motion where the requirements of s cial work render it advantageous.

T e accompanying drawings illustrate one convenient form in which the apparatus may be constructed, and insame: Figure 1 isA a side elevation, partly in-sectin, of the machine. Fig. '2 1s an end elevation thereof. Fig. 3 is a horizontal section, taken on the line 3-3, Fig. 1, looking in the direction of the arrow. Fig. 4 is a vertical section, taken on the line 4-4, Fig. 3, lookingV in the direction ofthe arrow, and illustrating one step in the operation of the machine. Fig. 5 is a view similar to that shown in Fig. 4, illustrating the same operation at a later stage. Fig. 6 is a part plan, and Fig. v7 an elevation, on a'larger scale, illustrating the corner folding or tucking in o ration. Fig. 8 is a sectional view of-a detailed partof the machine. Fig. 9 is a detail vIew, showing more clearl the means for operating the tuckin in evice. Figs. 10 and 11 rspective view, and a part sectional side eevation," tion of part of the machine.

In the form of machine illustrated in the drawings the folding die consists of a base plate 1 having four primary wing iecesQ -hinged thereto along its edge an ,correspending to the `s'ides of the box to be formed or coveredL and4 ap width to the depth o the box. 'To the to edges of these primary wings 2 are hinge secondary wings 3 .similar in length to the primary wings 2, but not so wide.

The' secondary Wings or have fixed thereto, overlapping pieces or trip fins 4, which proj the hinged edges 0f the seconda "y wings suiiciently to act as intercepti 'or trip levers whenever the dieis by suita forced through fold or close up e primary wings, .and by suchV action of the .trip fins or levers 4 the of s. modifica ect or overlap beyond' roximately equal in r Ico 3 are provided with, Y

rl le means I ide surfaces yadapted to secondary wings 3 `are turned down andi ably placed near each corner of the folding and guide the movable side members 11, and

die, and adapted,as the sides of the blank are folded up, to form corner folds o-f-the surplus material and tuck them in vbehind the side folds just before these are com-` pletely turned up. .The arrangement and operation of these tucking fingers will also be hereafter more fully described.

The folding die is preferably mounted in a suitable press, which, in the form shown in the drawings, com-prises a table 8 having suitable supports 9 and carrying fixed up' right' hollow side members 10, which support cross arms 12 and 13 of a sliding frame which is normally held in its highest or most extended position by springs 15, in the present instance conveniently contained, as

shown, in the hollow members 10, in which the members 11 of the frame are adapted to slide. Guide or-friction rollers 16 may also be provided for the sliding members 11, as shown. f v

The slidingframe carries, supported'by the cross arms 1 2, 13,' a. plunger 17 which is preferably telescopic by being slidable in a hollow member 18 fixed to the aforesaid cross-arms 12, 1 3. The plunger 17 is normally held in lts extended position by means of a coiled spring 19 (F 8) within the hollow member 18 and 'W ereb it has a vyielding action, the 'amount o which 4is capable of adjustment, as 'will hereafter be shown. The plunger 17 is provided with a plate 20,- adapted to receive and carry the box 20, shown in dotted lines in'Figs. 1 and 2 into the folding die and force it through or betweeng'uidi'ng surfaces, so as to fold up the primary wings .2. YA lso suitably and adjusta ly fixed to the cross arms 12, 13 of the slide, and outside the'plunger 17 are two pairs of arms '21,l 22, one air being oon- @nectedwith the arms 12a-n `the other air with the arms 13. These arms 21, 22, w ich Vmay betermed presser arms',-,are arranged to co-act with, or, afs. shown, to carry bars ,or surfaces 23, 24,{lvvliich c o-a'ct with the 9 secondary `wings 3 'ofithe folding die an'd ve Athem the final pressure uired to nish 'the complete turning in of t e covering blank. These presserarms 21, 22' may be constructed with side springs so as to .exert a more or less elastic ressureupon the secondarywmgs when t ey are mshing'ther action or the pressure may be increased'by `boxes of different sizes.

21 ma also, as s hown in Fig. 7, be made ad- '100 having them co-act with wedging surfaces fixed upon the plunger.

In some cases it is preferred to make one pair ofthe presser arms or the removable bars carried thereby somewhat longer than the other, as shown in the case of the pair 22 attached to the cross arms 13, so as to assist in turning down two of the covering flaps in advance of the others, and which, when the flaps have adhesive applied, prevents them interfering and so avoids the spreading of the adhesive upon the finished face of the covering materlal. The two extended presser. arms 22 thus lengthened are formed telescopic 'or sliding, the hollowv member 22"* of each containing a coiled spring 25 and being slotted at 26 (Fig. 1 to regulate or provide for the desired length of travel of the telescoping member 22, which travel is limited by a stud or projection 27. By this arrangement, when the final pressure is exerted to complete the covering or like operation, the springs yield and allow all the arms to become the same length. These presser arms, when considered together,.may conveniently be termed the second action of the machine, and in mostcases it is preferred to employ the presser arms 21, 22, as described for the second. action, and to -attach them to the cross arms 12, 13, by means of clamps 28, 29, so that they may be readily adjusted for the purpose of giving pressure upon all four sides of the box, or for operating upon The presser arms justab e in a vertical direction by providing them with slots and clamping screws 76 whereby their height vwith respect to the resser arms 22 maybe varied as desired.

oth pairs of res'ser arms 21, 22 may further be provi ed at their lower ends withslotsand screws, whereby the bars or sur- .faces 23, 24 areso Secured that they may be adjusted, or removed and replaced by ada ted to-t different sized boxes.

'-T e folding die' is provided preferably with a 'stern or shaft 30, adapted to carry and support and ide it in' its motion, and also to co-,act wit mechanism which actuates at the desired time` the tucking fingers G that form 'and turn in the corner folds of others the' covering blanks, and further b itsv spring action, hereinafter describe it causes orassists the folding die to return to` its normal position upon the upstoke of the sliding member, and at the same time it may eject the finished box. The return movement of the die stem ma be assisted, as hereinafter described, by t e contact of said stem, -or an extension 84 thereof, with a' 125 foot treadle 81 b means of which the machine is operate This die stem or shaft 30' carries on the inder sideof the die two ,fingers-or projections 31 (Fi 3, 7 and 9).,

adapted on the descent of* e die and its 130 stem 3Q to en age withvtrip levers 32 carried upon roc ing shafts 33, which shafts carry the tucking fingers 6 and impart motion to them, and thls motion of the tucking fingers 6 can be modified and vregulated at will, according to the character of the folds desired, as will be hereinafter shown.

On the under side of the die base plate 1, and supported from the die stem 30, are projecting fingers or cam actin surfaces 34 adapted to operate hinged c oser jaws 35 when, as shown'in the drawings, these latter are used, and said die stem 30 is adapted to telescope or slide in an outer hollow nmmber 36, the latter being'provided with a coiled spring 37 (Fig. '5) of sufficient strength to return said stem 30 to its normal or raised position, shown in Figs. 1 and 2, upon the ascent of the plunger 17. A stud 37"L projecting through a slot 3"(b in the hollow member 36 limits the travel of the die stem.

The air of hinged closer jaws 35 are ada te to act in conjunction'with apair of xed closer jaws 38, and both pairs 35 and 38 coact with and operate the folding die. The jaws 35 and 38 areA mounted in brackets 39 and 40, respectively, adjustably secured b clamping screws 41 or the like, passing through slots 8* (Fig.y 3) in-...the

Vtable 8 ofv the machine, which brackets are slidable in slide ways 42, `43 and. so laced that they surround and are parallel with the sides of the folding die and can be moved up and set just clear of its base plate lf'so that, when the die descends, its presser wings contact lwith the closer jaws and are causedY to fold up thereby. Upon the.re

'turn or upward movement ofthe folding die, the hinged closer jaws 35 are ret-urne to their normalposition 4by means of springs 52,V or by equivalent means. These closers are, as stated; in pairs 35 and 38, and are operated in pairs, and, as shown in the drawings, are placed atdifferent distances from the die, namely, the rigid set 38 being placed higher or nearer to the die than the hinged set 35. The effect of this arrangement is that in the covering o 4ration two opposite sides ofthe box are always turned up vand acted upon in advance ofl the other sides,

which prevents the adhesive, when used, be`

ingsqueezed out or smeared onto the inside of the box or finished surface of the maferial, and it also4 enables a much neater finish to be obtained upon the inside corners of the box. i

The pair .of hinged closer jaws 35 is' so mounted as to have their acting surfaces 44' at an angle with the line of motion oi the die, in the present example. these surfaces 44 being practically horizontal, while the acting surfaces 45 of the rigid closer jaws 38 are, practically vertical. this arrangement, and also of the position'- ing o f the two pairs ofjaws with respect The result of to the die, is that the rigid jaws 38 act upon the corresponding side or primary wings 2 of the die, and old them over before the hinged jaws 35 are turned up by the 4descending die and so turn their remaining pair of primary presser wings up into pos1t1on.

i V Instead of combining a pair of hinged closer jaws with a pair of rigid jaws, both pairs may be either hinged or rigid, but the combined arrangement described is preferable.

The rocker shafts 33, carryin the tucking fin ers 6, are mounted beneat 4the closer jaws a ove described in any suitable osi,- tion to be acted upon by the motiono the die through the medium of the fingers 31, which are adjustably mounted, and thetrip levers 32 before mentioned. In the machine illustrated a pairof rocker shafts is em,- ployed mounted in suitable bearingsetl carried by the brackets 40 of the rigid4 closer jaws 38. The rocker shafts are parallel with 4 each other and with the rigid closer jaws 38, and the tucking fingers 6 are mounted thereon so that they may be adjusted as to length of throw, angle of throw, and radius of throw, which enables practically any variety of corner fold to be readily obtained, and

further the distance between the tucking veniently obtained by providing them with slots 48 through which the rocker shafts 33 pass, said slots being placed radially with respect to the rocker shafts, sb that, as be fore stated, the angle, length and radius of the throw of the tucking fingers may be varied. The tucking fingers are tightened in the desired set osition'V on the rocker shafts i by means of a (justing nuts 49 adapted 4to ride upon threa ed port-ions of the rocking shafts, so that by suitably positioning the nuts the distance between the tucking fingers may be varied.

Thenocker shafts 33, vas already stated,

take their forward motion, to enable theV V tucking fingers 4to effect the tucking 4in opquick return motion to Withdraw said tucking fi ers, after the corners are tucked in and be ore the final closing up of the ends or sides of the box or blank is completed,

eration, from rthe trip levers 32, and their'f:

from springs 50 attachedthereto and to tl ic table 8` of the machine. The trip levers 32 arejreturried to their normal position by the return motion of the rocker shafts,l after they are released from fingers 31l by the continued ldescent of the die stem' 30,' and said trip levers 32 are so mounted upon the rocker shafts that, while they are rigid with respect to said rocker-shafts during the downward movement of the latter, they are free in the reverse direction, so that as the die and its stem rise the fingers' 31 raise the trip levers 32 out of their way, and then release said levers, which are given a quick or'escapement action by means of a spring 80, whereby they are caused t-o resume their original position to intercept the fingers 31 on the next downward movement of the die.

The plunger 17 and the telescoping presser arms 22 are permitted a yielding spring locking and releasing action, as already mentioned, and this spring action can -be regulated, as regards the pressure required to cause it, by the following convenient device, as 'illustrated Vin Fig. 8, applied to the plunger.

The hollow member 18 of the plunger 17 is provided with a hollow branch 51 extending therefrom at a right angle and containing a loose hard metal ball 53 adapted to be projected into the path of the plunger 17 by the pressure of a spring 54.- located behind said ball and in the branch 51. The pressure of the spring-is regulated by means of a regulating screw 55V which passes through the cap 56 of the branch 51 and compresses the spring 54, through the lmedium of a loose plunger .57, ja like loose plunger 58 beingpreferably interposed between the ball end of the spring V.'54 and the ball 53. The plunger 17 is provided with a slot 59, or groove, or the like, and the amount of pressure required to telescope the plunger is determined by the position ofthe ball 53 with respectto the slot, that 1s, the further the ball'projects into engagement with the slot 59, the greater the pressure required to telescope the plunger. This regulation is effected in some degree by means of a second regulating screw '55a which is carried by the plunger 17 itself, and projects into the slot 59 and contacts with the ball By these means the ball may be so positioned that the movement of the plunger will either push' it easily out of the way against the pressure of the spring 54, and so offer but little resistance tothe telescoping of the plunger, or the ball may be allowed to go so far into engagement v Offwith'thle slot 59 of the plunger that the telescopic movement of the latter is completely prevented. This arrangement provides an automatic locking and releasing action of the plunger 17. Said mechanism 1s, however, more particularly described and claimed in an application filed by meJune 1.4, 1906, Serial No. 321,601, and forms no part of the invention sought to .be claimed in this'ap'plication.

It is essential that the die base plate 1 should be perfectly truewiththe plunger plate 20, and to this end either the one or the other is made capable of adjustment. In

the present instance the plungerisniade universally adjustable, as shown in Fig. 8, by providing it with a ball socket joint 60 at its point of support in the cross-arms 12, 13 of the sliding frame, the ball 60 being split, as shown, and gripped by clamping pieces 61 adapted, when the necessary adjustment of the plunger plate has beenmade, to be tightened on the split ball 60 by screws 62. Instead of the plunger 17, the. die stem 30 may be the adjustable member, by providing it, where it passes through the table 8 of the machine, with adjustable bearings. It is preferred, however, to employ the above described arrangement.

-As before stated, some additional pressure may be given to the hinged closer'jaws 35'to insure that they firmly press the secondary wings and'the covering blank against the sides of the box, by providing the presser arms 21 with side plates consisting of enveloping pieces 63, hinged or movably attached thereto at 64 and having a more or less yielding action imparted to them by springs 65, which action is adjustable by the regulating screws 66, as shown in Fig. 1.

In covering or making up flanged boxes, the modified form of folding die shown in Figs. 10 and 11 is employed, and from which it will be seen that the primary wings 2 are made slightly thicker than the width of the flange G8' of the box or lid G9, and they are hinged to the base 1 of the die. at 70, as shown, upon their outside edge so that as they are turned up their lower inside edges 71 gradually fold over the flange 68 and exert a pressure upon its whole surface, thus firmly gluing it down,.if adhesive has previously been applied to th'e proper part of the box blank or covering blank. For this function of the machine, that'is, covering the flanged lids, the lower edge 71 of the primarywingsmay be coated with an-elastic material or pneumatic pad adapted to give, yielding pressure. This form of die is provided with secondary wings 3 and trip fins 4 as before, which may also be provided with pneumaticl or elastic pads, if desired, and such pads may be employed' for other than flanged boxes. In making flanged boxes as above described it is preferred to employ blanks previously scored or creased.

The machine above described may be -operated by hand, foot, or other power, a convenient arrangement being to extend the movable side members 11 so that they pass lthrough the hollow side members 10 on the lows: The box body or lid 20 is placed upon the inside the box where itl is caused tol the plunger plate 20, as shown in dotted lines in Figs. 1 and 2, upon which it fits sufficiently tight to hold by friction. The covering blank 79 is then placed upon the folding die so that it is centered to properly register with the box body or lid.. The slid ing frame is next lowered by the depression of the foot treadle 81, or by other suitable means, causing the plunger 17 to descend, carrying with it the box body or lid 20a, until it reaches the base plate 1 of the folding die. The continued; motion of the plunger' 17 then forces the folding die and its spring supported stem 30 first through the rigid closer `jaws 38, which operate to fold up the corresponding pair of primary wings o the die 2, after which the tucking fingers 6 are brought into operation by the projections 31 engaging with the trip levers 32 of the rocker shafts 33 to tuck in the corners of the covering blank, as shown in Figs. 6 and 7, when, on the release and quick return of the trip levers 32 from the projectionsl, by the further descent of the die stem 30, the rocker shafts and tucking iii fin ers' are also returned to their normal positions, as shown in dotted lines kin Fig. 7, bythe action of the s rings 50and then through the continued ownward motion of the plunger 17, the hinged closer jaws 35 (Fig. 4) are` turned up vertically by the fingers 34 to fold up the remaining pair of primary wings, thus pressing the covering lank up against the sides of the box blank, as shown in Fig.y 5. Following on the withdrawal ofthe tucking fingers 6 is the action of initially turning over the secondary win 3 by the en agement of the trip fins 4 with the edges o the closer jaws 3538 to complete the covering operation by turning the edges of the blank over to the inside of f the box body or lid, the .bars or surfaces 23, 24 carried by presser arms 21, 22, which descend with the plunger, continuin -their'de scent untilV they contact with an second-ar Fig. `5, tlius forcingthe covering blank Von `adhere firmly, if an adhesive has been used. --The covering or folding o eration being now completed, and .the lunger havin yreached the lowest point. its travel wit the arts in the respective positionsshown in ig, 5, the treadle 81 or the like is released,`and the springs of the movable side members 11 return -the side members andplungerto'their original Aposition (Fi s; 1 and' 2), the die stem 30 yand the ldie f o lowingby reason 'of lthe spring 37, which may be augmented by the upward motion of the treadle .81 contacting with extension 84r '.therebf, while the sprngs52 turn the hinged closer jaws also to their normal position,

force the wings 3 to the position shown inl thus leaving the finished article ready for ejection from the machine. In order that the plunger 20 and the presser' bars 24 may be automatically limited in their downward movement, independent of the pressure applied to the'treadle 81, the spring locking and releasing mechanism, hereinbcfore de scribed, is employed. Thus by adjusting the balls 53 said mechanisms may be set to automatically release the plunger 2O and presser bars 24 at the moment that the box cover is fully applied, so that a further downward movement of the treadle 81 will not carryv with it thev said plunger and presser bars.

For the purpose of ejecting the finished carryingthe box. Then, when the slide rises on its u ward stroke under action ,of its spring, t e cross head 88 thereof, as shown, comes into contact with the piston 86 and forces the air through the tube 87 in a quick 4ufl" underneath the box or lid, thus removing it-from the pad, and the jet may be so directed as to carry the box away from the plunger in any convenient direction into anyv suitable chute.

n some cases the diecan be worked without primary wings by having swinging closers which may have on their upper edge secondary wings with trip fins adapted to .turn over the llap of the covering blank.

For Vsome kinds of work I can place the lprimary and secondary wings on-the closers,

soy

machine can be' ari-an ed to work either by powe or by hand an foot power.

In t e, o ration of making a box or lid,

as distinguished from covering a previously formed box or 1id it will be understood that the same is accomplished by lacing upon the folding` die a blank of suita le shape and of the proper thickness of material, whether paper or metal, whereupon the downward movement of the lunger will form the complated boxor lid in a. mannersimilar to that# escribe'd in respect to the covering operation.r
